Project Echo - Wikipedia
Project Echo was the first passive communications satellite experiment. Each of the two American spacecraft, launched in 1960 and 1964, were metalized balloon satellites acting as passive reflectors of microwave signals.
Echo: The Ancestor of NASA's Communications Satellites
Decades before satellite TV or GPS, NASA used a huge silver balloon to prove global communications via satellite possible. This was Echo, the U.S.’s first communication satellite, which paved the way for many current communication technologies.
Echo, NASA's First Communications Satellite - NASA
2008年3月23日 · Echo, NASA's first communications satellite, was a passive spacecraft based on a balloon design created by an engineer at the Langley Research Center. Made of Mylar, the satellite measured 100 feet (30 meters) in diameter.
Echo | Communication, Imaging & Navigation | Britannica
Echo, either of two experimental communications satellites launched into orbit around Earth by the National Aeronautics and Space Administration (NASA) during the 1960s. Consisting of aluminum-coated Mylar balloons that were inflated after launching, the Echo satellites were passive instruments—i.e., they simply reflected radio waves back to ...
August 1960 - Project Echo Launched - NASA
2024年8月5日 · Project Echo was launched. Echo originally started as a 30 inch balloon for the payload of Vanguard to observe atmospheric drag once released into the atmosphere. Engineers realized that a bigger balloon (100 foot) would provide more opportunities to conduct experiments.
Echo 1 Communications Satellite - National Air and Space Museum
Launched in 1960, Echo 1 was designed to explore the new field of communications via space. Its design was remarkably simple: Essentially a large balloon, measuring 30 meters (100 feet) across, the satellite provided a reflective surface in space.
This Month in NASA History: The “Satelloon” Takes to the Sky
2010年8月12日 · Fifty years ago this month, NASA jump-started the telecommunication revolution with a balloon. Echo 1, conceived by Langley Research Center’s William O’Sullivan, was launched on August 12, 1960. Nicknamed the “satelloon,” the 100-foot wide Echo 1 was the world’s first communication satellite.
